WASTE PTFE FITTING Filed July 23, 1951 1119101 @Wl/MMM "lil Patented May 24, 1932 UNITED s'r DAVID H. EBINGER, F COLUMBUS, OHIO, ASSIGNOR TO THE D. A. EBINGER SANITARY MFG. COMPANY, OF COLUMBUS, OHIO, ACORPORATION OF OHIO WASTE PIPE FITTING Application filed July 273,

This invention relates to waste pipe fittings and more particularly to that type of fittings adapted for use in connection with sinks and similar fixtures and wherein the fitting not only constitutes a coupling for connecting the sink to a waste pipe or drain conduit, but also provides in connection therewith a stopper or valve member movable within the coupling or fitting from seated t0 unseated positions.

It is also an object of the present invention to incorporate in such a fitting novel means for effecting the. raising and holding of the valve or stopper member in an un- 5 seated position so that the liquid may have a full passage through said fitting and into the waste line.

Another object of the invention is to provide in connection with a fitting of this char-v acter a. strainer member in the form of a basket which may be removed for emptying or cleaning purposes without effecting the actuation of the stopper member.

The stopper member in turn may also be operated from a closed to an open position without interfering with. the basket or strainer member.

A further object of the invention is to provide a sink with an outlet openinghaving an angular downwardly projectingneck in the shape of a. funnel located below said outlet and which neck or funnel is of such size asto accommodate the basket positioning the .I same so that its upper end is below the upper surfacevof the sink bottom and thereby causing'the water to Vflow into the basket through the open top thereof with the particles of foreign matmr therein, which will thus be collected in the basket or strainer member..

Vith these and other objects in view, which will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangement of parts hereinafter to be more pointed out in the ap- 1931. serial N01. 552,648.

pipe fitting comprising the present invenion,

Figure 2 is a top plan view thereof,

l Figure` 3 is a horizontal sectional view taken on the line 3-3 of Figure l,

Figure 4 is a detail enlarged vertical sectional view showing more in detail the means for retaining the stopper member in its elevated position. Referring more particularly to the drawings the numeral l designates the sink formed with the usual outlet in the bottom 2 thereof. Formed integrally with the bottom 2 and located around the outlet is an angular downwardly projecting neck or funnel shaped eX- tension 3 and arranged in alignment therewith and extending downwardly therefrom is a waste pipe Il. Thispipe has its upper end flared and enlarged as at 5, and formed with an outwardly extending flange 6 between which and the lower end of the neck exten* sion 3 is positioned a suitable gasket 7 The waste pipe is internally threaded for the reception of a similarly threaded lower end of a tting 8 which constitutes the coupling between the waste pipe 4 and the sink 1 and to which the present invention is particularly directed.

The fitting 8 is in the form of a sleeve and has its upper portion enlarged as at 9 and positioned within the extension 3 so as to bear against the inner surface thereof. In connecting the waste pipe to the sink the fitting 8 is inserted downwardly through the extension 3 and into t-lie upper end of the waste pipe threaded thereinto, drawing the flange 6 tightly against the gasket 7 with the enlargement 9 bearing against the inner sur` face of the extension 3 a distance above the lowerinost end thereof. In a general way this construction is commonly employed for attaching the waste pipe to sinks, wash bowls, or the like.

Positioned-for vertical movement within the fitting S is avalve or stopper member l0 formed to include a tapered head 11 adapted for normal engagement with the similarly tapered seat 12 formed interiorly of the fit- Y ting 8 and at the lower end thereof. Arising centrally from the 'head l1 is a stem 13 which has an intermediate port-ion received within an opening formed in a strainer plate 14 rigidly secured to the enlargement 9 by means of screws or other fastening elements 15. rl'he plate 14 serves to guide the stopper member in a vertical movement from a closing to an opening position. To retain the stopper member in its elevated position, there is provided on the under side of the plate 14 a circular body 16 having a reduced extension 1'? positioned through the central opening formed in the plate 14 peened over, riveting the same to the plate member. Formed in the member 16 is a pair of diametrically opposed bores 1S in which are positioned balls 19 which are resiliently held against the stem 13 by means of springs 20 confined within the bores 18 by means of a band 21 surrounding the body 16. The springs 20 which are held compressed within the bores will cause the balls 19 to move inwardly towards each other upon the raising of the valve or stopper member and position themselves under a shoulder 22 formed by reducing the stem 13 at its lower end thereby holding the stopper in its elevated position as disclosed by dotted lines in Figure 1. In order to manipulate the stop-l per member the stem 13 has its upper end reduced as at Q3 forming a knob 24 providing a .finger hold. This construction of the stopper member and the retaining means therefor permits the stopper member to be rotated axially and may beheld seated or unseated in any revoluble position within the coupling or fitting in contrast to many ordinary constructions wherein it is necessary to seat the stopper in a predetermined position or one of a number of predetermined positions in order to effect the movement thereof to seat and unseat the stopper, and, moreover, to turn the stopper to a predetermined position of a revolutionv when raised to a position in which the stopper is unseated in order to maintain the stopper in this position. The present construction overcomes this precision in placing parts and will hold the stopper memF ber in either its raised or lowered position by simply manipulating the latter in a straight vertical plane.

Positioned above the plate 14 and within the funnel shaped extension 3 is a strainer dish or basket 25 which is of considerable depth and has its upper edge 26 arranged slightly below the upper surface 27 of the sink bottom. The circular side wall of the basket 25 is formed to snugly fit and conform to the tapered inner wall of the extension 3 to form a tight joint therebetween and prevent any particles of foreign matter from passing therethrough but will flow into the basket and out through the fitting into the waste pipe collecting any .such articles of foreign matter which are too large to pass through the perforations in the basket. In order to effect the removal of the basket from its engagement within the sink a handle 28 is provided centrally of the basket and is so shaped as to have a portion on each side of the stem 13. The handle clip 28 is also provided with an opening through which the .stem 13 extends by which the basket is guided when positioned within the extension 3 of the sink. It will be noted that the basket may be seated in any rotatable position within the sink body and upon the stem 13 and that the same does not interfere with the actuation of the stopper member, the operating portions of the handle clip 28 being so spaced that access may be had to the stem 13 therebetween.

it will be apparent from the foregoing that a waste pipe fitting construction has been provided with a stopper member and a strainer basket is associated therewith which may be operated independently of one another. Either lthe strainer basket or the stopper member may be turned or seated in any position. The stopper may be opened by merely raising up on the stem and held in its raised position by the resilient action of the spring pressed balls. rlhe balls in no way interfere with the revolving of the stopper' in order to form a better seat as, for example, by crushing or grinding particles of matter which may adhere to the tapered face of the stopper, or to its seat, or for other purposes. The fitting is extremely simple in its con struction', efficient in its, operation, reliable and comparatively economical and simple to manufacture.
